ASTM A302 grade C Mn-Mo-Ni steel A302 Gr.B steel plate is a low-alloy high-strength steel containing Mn, Mo, and Ni elements, with both high tensile strength and high temperature resistance. It meets the ASTM A302 standard and is designed specifically for medium to high temperature pressure vessels. It has excellent creep resistance and is suitable for long-term high-pressure environments.
Application and Performance Advantages
ASTM A302 grade C Mn-Mo-Ni steel A302 Gr.B steel plate is widely used in the manufacturing of petrochemical and nuclear power equipment, such as reactors and boilers. Its high strength and low temperature impact toughness can cope with extreme working conditions, and its low alloy composition simplifies welding processes, improving processing efficiency and structural reliability.
Manufacturing process characteristics
By adopting the normalizing and tempering process, the grain structure and mechanical properties are optimized, and the purity is strictly controlled during the smelting process to ensure the uniformity and stability of the material. ASTM A302 grade C Mn-Mo-Ni steel A302 Gr.B steel plate also has excellent weldability and heat treatment stability, meeting the requirements of high temperature and high pressure equipment.
